This triangle is also called a drafting triangle, hence the name. [1] This triangle is also half of an equilateral triangle , and a polydrafter's cells must consist of halves of triangles in the triangular tiling of the plane; consequently, when two drafters share an edge that is the middle of their three edge lengths, they must be reflections ...
The size of a book is generally measured by the height against the width of a leaf, or sometimes the height and width of its cover. [2] A series of terms is commonly used by libraries and publishers for the general sizes of modern books, ranging from folio (the largest), to quarto (smaller) and octavo (still smaller).
The geometrical solution of the construction of Van de Graaf's canon, which works for any page width:height ratio, enables the book designer to position the type area in a specific area of the page. Using the canon, the proportions are maintained while creating pleasing and functional margins of size 1/9 and 2/9 of the page size. [6]
Front cover of the St Cuthbert Gospel, c. 700; the original tooled red goatskin binding is the earliest surviving Western binding.. A book cover is any protective covering used to bind together the pages of a book.
The spine of the book is an important aspect in book design, especially in the cover design. When the books are stacked up or stored in a shelf, the details on the spine is the only visible surface that contains the information about the book. In a book store, it is often the details on the spine that attract the attention first.
Triangles have many types based on the length of the sides and the angles. A triangle whose sides are all the same length is an equilateral triangle, [3] a triangle with two sides having the same length is an isosceles triangle, [4] [a] and a triangle with three different-length sides is a scalene triangle.

The lead section should summarise with due weight the life and works of the person. When writing about controversies in the lead section of a biography, relevant material should neither be suppressed nor allowed to overwhelm: always pay scrupulous attention to reliable sources, and make sure the lead correctly reflects the entirety of the article.
Twelve key lengths of a triangle are the three side lengths, the three altitudes, the three medians, and the three angle bisectors. Together with the three angles, these give 95 distinct combinations, 63 of which give rise to a constructible triangle, 30 of which do not, and two of which are underdefined. [13]: pp. 201–203
